Writing in Holding Registers [10h]:
This function writes data in consecutive holding registers. An example follows:
• Write “3000 seconds” as the first acceleration time 1 (F002) in an inverter having a
slave address “1.”
• This example uses change data “300000(493E0h)” to set “3000 seconds” as the data
resolution of the registers “0024h” and “0025h” holding the first acceleration time 1
(F002) is 0.01 second.
When writing in selected holding registers fails, see the exception response.
